3. Introduction
This presentation is about:
– development practices
– personal development

4. DEVELOPMENT PRACTICES

5. 1. Coding standards
• Readable code
• Easy to maintain
• Documentation

6. <?
// Method 1
if($condition)
function1($a, $b, $c);
if($i < 7 && $j > 8 || $k == 4)
a($i);
?>

7. <?php
// Method 2
if ($condition)
{
getUser($id, $username, $key);
}
If (($i < 7) && (($j < 8) || ($k == 4)))
{
displayGraph($value);
}

8. • PEAR Coding Standards
http://pear.php.net/manual/en/standards.php
• Zend Framework Coding Standards
http://framework.zend.com/manual/en/coding-standard.html
• eZ Components Implementation guidelines
http://www.ezcomponents.org/contributing/coding_standards

9. 2. Code Commenting
• Reduced code understanding time
• Serves as a documentation
• Answer the question: WHY??

10. /**
* Add number
*
* This function will take two integer numbers and will
* return the addition result of them.
*
* @param int first number
* @param int second number
* @return int addition result
*/
function addNumbers($firstNum, $secondNum)

11. 3. Code re-use
• Re-use code across projects
• Refactor every now & then
• Don’t Repeat Yourself (DRY)

12. 4. Code testing
• Gives confidence
• Unit testing in rescue
• Test Driven Development (TDD)

13. • PHPUnit - http://www.phpunit.de
• SimpleTest - http://www.simpletest.org

14. 5. PHP Framework
• Forces good structure
• Ready to use libraries
• Solves most real-life problems
80% - 20%

15. • Zend Framework - http://framework.zend.com
• CodeIgniter - http://www.codeigniter.com
• CakePHP - http://cakephp.org/
• Symfony - http://www.symfony-project.org

16. 6. Source Control (SCM)
• Your own personal UNDO
• Compare, rollback, track source code
• Must for team collaboration

17. • Subversion - http://subversion.tigris.org
• Git - http://git-scm.com

18. 7. PHP IDE
• Increased productivity
• Reduced error in code
• Debugging, profiling
